The first objective of this study was to investigate the effects of the CE and SE on the subsequent reproductive performance and milk production of dairy cows in Brazilian herds, and the second objective was to evaluate the reproductive performance and milk production of dairy cows according to the positive or negative isolation of bacteria in the uterine environment. A total of 279 lactating Holstein dairy cows (28\u201333\u2009days in milk) from six commercial farms were studied. These were classified into three groups: healthy cows (without CE and SE, <jats:italic>n<\/jats:italic>\u00a0=\u00a0161), cows with CE (vaginal discharge score\u00a0=\u00a03 and \u226518% PMNL, <jats:italic>n<\/jats:italic>\u00a0=\u00a083) and cows with SE (absence of signs of CE and &gt;18% PMNL, <jats:italic>n<\/jats:italic>\u00a0=\u00a035). According to the presence of bacteria isolated from the uterine environment, the animals were classified as healthy cows (<jats:italic>n<\/jats:italic>\u00a0=\u00a0161), CE cows with positive (<jats:italic>n<\/jats:italic>\u00a0=\u00a068) and negative (<jats:italic>n<\/jats:italic>\u00a0=\u00a015) bacterial isolation; and SE cows with positive (<jats:italic>n<\/jats:italic>\u00a0=\u00a021) and negative (<jats:italic>n<\/jats:italic>\u00a0=\u00a014) bacterial isolation. Cows with CE (20.5%) and SE (31.4%) had a lower (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.05) conception rate at first AI than healthy cows (47.8%). Furthermore, both cows with CE (3.1) and SE (2.8) needed more service to become pregnant than healthy cows (1.7) and more days to be pregnant (50.3\u2009days in CE and 43.1\u2009days in SE than healthy group; <jats:italic>p<\/jats:italic>\u2009&lt;\u2009.001). Cows with CE (23.8\u00a0kg) and SE (23.7\u00a0kg) produced less milk than healthy cows on the day of sampling (28.2\u00a0kg); however, milk production during 305 DIM of cows with CE and SE was not impaired when compared to healthy cows. The logistic regression showed that parity, body condition score, 305\u2009days milk production, last calving (eutocia or dystocia), twin birth and stillbirth were not associated with the incidence of CE and SE. In addition, we highlight that cows with CE and SE, but with negative bacteria isolation, did not have reproductive performance and milk production impaired during the postpartum period. These results support that the use of antibiotics would not be beneficial in these cows, contributing to the strategic and rational use of antibiotic therapy on dairy farms.<\/jats:p>","DOI":"10.1111\/rda.14301","type":"journal-article","created":{"date-parts":[[2022,12,13]],"date-time":"2022-12-13T07:43:55Z","timestamp":1670917435000},"page":"414-422","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Evaluation of clinical and subclinical endometritis impacts on the reproductive performance and milk production of dairy cows in Brazilian herds"],"prefix":"10.1111","volume":"58","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1039-371X","authenticated-orcid":false,"given":"Renan Braga","family":"Paiano","sequence":"first","affiliation":[{"name":"Department of Animal Reproduction, School of Veterinary Medicine and Animal Science University of S\u00e3o Paulo  S\u00e3o Paulo Brazil"},{"name":"Department of Population Medicine University of Guelph  Guelph Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5664-0096","authenticated-orcid":false,"given":"Jeannine","family":"Bonilla","sequence":"additional","affiliation":[{"name":"Department of Food Engineering, College of Animal Science and Food Engineering University of S\u00e3o Paulo  Pirassununga Brazil"},{"name":"Department of Food Science University of Guelph  Guelph Ontario Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guilherme","family":"Pugliesi","sequence":"additional","affiliation":[{"name":"Department of Animal Reproduction, School of Veterinary Medicine and Animal Science University of S\u00e3o Paulo  S\u00e3o Paulo Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3290-566X","authenticated-orcid":false,"given":"Andrea Micke","family":"Moreno","sequence":"additional","affiliation":[{"name":"Department of Preventive Veterinary Medicine and Animal Health, School of Veterinary Medicine and Animal Science University of S\u00e3o Paulo  S\u00e3o Paulo Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6773-4450","authenticated-orcid":false,"given":"Pietro Sampaio","family":"Baruselli","sequence":"additional","affiliation":[{"name":"Department of Animal Reproduction, School of Veterinary Medicine and Animal Science University of S\u00e3o Paulo  S\u00e3o Paulo Brazil"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,1]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.5424\/sjar\/2015134-8129"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.theriogenology.2015.09.043"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.3168\/jds.2018-16001"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.3168\/jds.S0022-0302(94)77212-X"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.theriogenology.2015.10.045"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.3168\/jds.2016-11373"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.3168\/jds.2012-5682"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.3168\/jds.S0022-0302(97)76275-1"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.3168\/jds.2014-8462"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1099\/jmm.0.035774-0"},{"key":"e_1_2_10_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.theriogenology.2003.03.001"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1111\/asj.12219"},{"key":"e_1_2_10_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.tvjl.2007.12.019"},{"key":"e_1_2_10_15_1","doi-asserted-by":"publisher","DOI":"10.3168\/jds.S0022-0302(02)74302-6"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.3168\/jds.2018-15383"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.3168\/jds.2012-6269"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.3168\/jds.S0022-0302(01)74600-0"},{"key":"e_1_2_10_19_1","volume-title":"Nutrient requirements of dairy cattle","author":"NRC","year":"2001"},{"key":"e_1_2_10_20_1","first-page":"164","article-title":"Metritis and endometritis in high yielding dairy cows","volume":"39","author":"Opsomer G.","year":"2015","journal-title":"Revista Brasileira de Reprodu\u00e7\u00e3o Animal"},{"key":"e_1_2_10_21_1","unstructured":"Paiano R.
